I want to go for a few day hiking trip, where I would make 10+km per day, the problem is every time I do more than 10km hiking I end up with blisters, so taking a longer trip would be a problem.

What the fuck am I doing wrong? I used to use military boots, they cant be fucking bad despite what anons say, soldiers walk in them an live.
Not to mention back in the day people use much more primitive, heavy, leather boots and didn't complain.

I've been using Grom Protektor boots for years, they are decent, breathe well, light, I don't think its their problem.
is it the socks? Should I invest in those marino wool socks?
I heard mountain hikers use thick wool socks even in the summer, I honestly cant imagine doing that, won't it cook my feet?

One issue i have no matter what boots I wear, there's always some minimal friction, no matter how tight I tie the lases (I know they cant be too tight) I'm guessing that might be the reason I get blisters after a longer walk.

Should I just buy fucking Lowas? God fucking dammit.
